Saloni Kumari

I’m an aspiring MERN Stack Developer and B.Tech IT student focused on building RESTful APIs, secure backend systems, and AI-integrated web applications. I enjoy turning well-defined requirements into reliable, testable features that users can trust. In my projects, I built a UPI-style backend REST API with Node.js, Express.js, and MongoDB, including atomic debit/credit transactions using idempotency keys to prevent duplicate payments. I also implemented secure authentication using JWT and bcrypt, plus automated email notifications with Nodemailer. I’ve also developed a full-stack AI chatbot application with a React frontend and a Node.js/Express backend, integrating the Google Gemini API for intelligent, context-aware responses. My approach is hands-on, security-minded, and grounded in strong fundamentals like DSA, DBMS, and OOP.
